I just got to this thread. I remember reading some years ago( I've been trying to find where I read it) where a poodle had a large cancerous mass in his chest, and it was pushing the other organs to the side . The vet said to put the dog down. Instead, the dog was given , over time ( I don't remember them saying how much at each dose) two bottles of bovine cartilage and the mass dissolved to the complete astonishment of everyone involved . Health food stores sell bovine cartilage.
